HINGED EXTENSION FOR HAY-CARRIER TRACKS- Specifieation of Letters Patent.

Patented April 30, 1907.

Application filed January 3,1907. Serial No. 350,696.

To all whom it may concern:

Be it known that I, JEROME A. Gnoss, a citizen of the United States, residing at Fultonville, in the county of Montgomery and State of New York, have invented certain new and useful Improvements in Hinged Extensions for Hay-Carrier Tracks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in hinged extension tracks and hoisting apparatus, and consists essentially in the provision of a hinged track con nected at one end to a stationary track adapted to be supported from the ridge of a building and so arranged that when it is swung into operative position, may be supported in such position and automatically open a door in a building and through which the track extends when adjusted for use in hoisting.

The invention consists in other details of construction and combinations and arrangements of parts which will be hereinafter fully described and then specificall y defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which:

Figure 1 is a perspective view showing my improved hinged extension track and hoisting apparatus adjusted for use within a] building, showing the door raised and held open by the extension track. Fig. 2 is a side elevation of the carrier at the end of the hinged extension track. Fig. 3 is a sectional view on line 33 of Fig. 2. Fig. 4 is a side elevation of the apparatus for holding the extension track suspended. Fig. 5 is a section on line 55 of Fig. 4. Fig. 6 is a side elevation of the hinged joint and parts immediately connected thereto, and Fig. 7 is a side elevation of a portion of the extension track and illustrating the same as bolding a door open.

Reference now being had to the details of the drawings by letter, A designates a hanger which is mounted upon a rod A which is fastened by means of lag screws A or other suitable fastening means to the beam A securely held to the ridge of a building. Said hanger is slotted longitudinally at one end to receive the plate B which is either i11- tegral with or fastened to the hinged extension track C. Said plate B has a curved slot B formed therein, as seen by dotted lines in Fig. 6, and a pin (1 passes through the walls of the slotted end of the hanger A and also through said slot B, and serves to guide the extension beam in its pivotal movements. The plate B is pivotally mounted upon a pin (J which also passes through the walls of the slotted portion of the hanger.

Projecting from the opposite sides of the hanger are the flanges C, the rear ends of which terminate in shoulders C upon which the permanent tracks C are adapted to rest, with their upper faces [lush with the upper faces o'f'the flanges C there being one upon each side of the hanger. Said extension track C has the lateral flanges O' 'which, when the track is extended to the position shown in Fig. 1 of the drawings, connect with the flanges 0, whereby the carrier may travel by the hanger and onto the permanent tracks C". It will be noted upon reference to Fig. 6 of the drawings that the hanger has a recess a formed horizontally in the under surface thereof and which is for the reception of the meeting end of the permanent track which, in the present instance, is shown as substantially inverted Ushape as illustrated in Fig. 1 of the drawings. Suitable bolts or other fastening means may be employed for holding the permanent track to the hanger, and auxiliary means, such as hooks D, as shown in Fig. l of the drawings, may be fastened to the permanent track and connected to eyebolts D held to the beam A. Said extension track, which is normally held at an inclination when adjusted for use, has its forward end slightly upwardly turned, forming a portion which is substantially level for the purpose of allowing the carrier to properly receive the traveling pulley with its load which it could not do if the carrier rested at an incline. The carrier after having secured its load and having been released from the fixed lock attached near the end of the track, has an upward grade to make which causes the carrier to start ofl' gradually without jerk or shock; also when the empty carrier is being returned to end of track, it will practically run down this grade from its own gravity with momentum sufficient to carry it upon the level section of track, release the traveling pulley and lock itself to track ready to receive another load.

The carrier, designated in Fig. 2 of the drawings, consists of the frame E in Which the wheels E are mounted to travel upon the two flanges C, one upon either side of the extension track, and E designates a grooved sheave also journaled upon the hoisting frame and about which a rope or cable E passes which also passes about a grooved sheave F which is supported thereby, one end of said rope or cable being fastened to an extension of said hoisting frame, as shown clearly in the drawings. In order to limit the outer movement of the frame of the carrier, an upturned flange G is formed at the end of the extension track, against which the outer of the wheels E are adapted to contact. The under portion of the carrier frame is arched, as shown at H, and is provided with an aperture h at the highest portion of said arch and adapted to receive a lug I formed upon the end of the resilient bar 1, whereby, when the carrier is in the position shown in Fig. 1 of the drawings, it may be held in such position until a load is hoisted and in readiness to be drawn'up the inclined extension track and upon the permanent or fixed track. J designates a yoke carrying the pin J upon which the sheave F is j ournaled, and the upper end of said yoke terminates in a point J 2 which is adapted, as the yoke J is raised, to its highest limit, to contact with the lug I and throw the same out of the aperture formed in the arched portion of the frame E whereby the carrier may be released. A hook J 3 is formed at the lower end of the yoke J and to which the material to be hoisted may be connected.

Referring to Figs. 1 and 4 of the drawings, will be seen a bracket arm K fixed to a cross beam N, and the lower end of said bracket arm terminates in a hook K adapted to receive the clevis O which is pivotally mounted upon a pin 0 passing through the truss Q which is fastened to the extension track, said truss being connected to the track by the braces Said clevis has an eye 0 shown clearly in Figs. 1 and 4 of the drawings, and through which a rope L is adapted to pass, which rope passes over a sheave 1? supported by the bracket arm K, and thence underneath a sheave l5 fastened to the plates Q connected to said truss members and thence fastened at P to the end of the bracket arm K. Said rope L is for the purpose of causing the clevis O to be swung over the hook K when the extension track is raised to an operative position.

M designates an opening in the end of the building, said opening being closed by the doors M, and the upper portion of the opening M is contracted, as at m, which contracted portion is adapted to be closed by means of an outwardly swinging door M the doors M swinging into the building, as will be noted upon reference to Fig. 1 of the drawings. Upon the upper edges of the forwardly extending truss beams Q is a buffer B, shown clearly in Fig. 7 of the drawings, and against which a projecting portion IV of the outwardly swinging door M is adapted to contact when the extension track is adjusted for use, said buffer holding the door open and out of the paths of the wheels E upon the con- 'veyer frame.

The operation of my apparatus will be readily understood, and is as follows. When not in use, the extension track is positioned inside the building, as shown in dotted lines in Fig. 1 of the drawings, and when adjusted for use, in the position shown in solid lines in Fig. 1 of the drawings. As the extension track is thrown to the position shown in solid lines in Fig. 1, the buffer R coming in contact w1th the extension M upon the swinging door 1\ 2 will cause the latter to open to the position shown in dotted lines in Fig. 1 of the drawings. 1 When the extension track is raised to its highest limit, the clevis 0 may be thrown over the hook K by means of the rope L, thus holding the track suspended. As the carrier reaches its outer limit, it is automatically held by means of the lug I upon the resilient bar I and when the sheave F is hoisted so that the point J will contact with the lug h, the carrier will be released, and as power is applied to the rope E which extends into the building and preferably over a sheave not shown, the carrier frame with its load may be gradually started upon the extreme end of the extension trackwhich is substantially level and thence drawn up the inclined extension track by the hinged connection and upon the permanent track and conveyed to anylocation where it is desired to release the load. The carrier may be returned to its starting position either by gravity or by means of a rope or cord which may be attached thereto and extend down to any suit able location. When it is desired to throw the apparatus out of an operative position, the clevis may be detached from the hook upon the bracket arm K and the hinged track lowered through the opening M of the buildin and as the extension track lowers, the door 1N1 will fall closed.
